dizzy. on my turbo hatch
 

ok i just picked up a h22 hatch turbo, with no dizzy. according to the owner before me the dizzy was set at 6 degrees before TDC. what is the best way to go about putting a new dizzy in with out affecting the already done tune. thanks for the help in advance

Get a timing gun and set the timing again.

will that hurt the tune at all at idel

6 before TDC sounds really low, but if that's what it was tuned with then yes just get a timing light and set it back to 6

platinum.
